Submitting an application to connect initiates key activities in the connection process. Connection Applicants should submit their application to AEMO, together with all outstanding information requested by AEMO in its connection enquiry response.

AEMO will advise the applicant of the additional information required before the application can be processed. The requirements of a complete application are covered in the Connection Application Checklist.

If AEMO’s technical information requirements are not met, the application is incomplete and cannot be processed.

AEMO will assess the application to connect together with the proposed performance standards. At the conclusion of this stage, AEMO will notify the Connection Applicant of AEMO’s agreement to the performance standards and the outcome of the system strength impact assessment with any requirement for System strength remediation (clause 5.3.4A and 5.3.4B of the Rules).

At this stage, AEMO will also assess the need for network augmentations and their contestability. Augmentations to the interface to the DSN are not contestable, and can only be effected by the incumbent Declared Transmission System Operator (DTSO). For the remaining contestable parts of the augmentation, the Connection Applicant may conduct an invitation to tender (ITT) to select suitable service providers, or request AEMO to do so.
